Sorry I have downloaded the 1.8.0 soft, in the b9 web site in documentation software overview is wrote:
"I’ve selected the Open button, there is an existing layout called Eiffel Tower, I’ll go ahead and open that, it will import the data from the STL file and give us a graphical representation of the object that we are wanting to layout to prepare for printing. Now, we can add other STL files, we can create supports, we can do a number of operations, but the layout function is how we basically set up the models and prep them to be sliced before we print them."
Sorry but i didn't find this file in the bc9 where is? Or is writing for sample?
